Zosterops splendidus
The Ranongga White-eye (Zosterops splendidus) is a captivating, small passerine bird, endemic to the volcanic island of Ranongga in the Solomon Islands. Measuring approximately 11-12 centimeters in length and weighing around 8-12 grams, this species exhibits the characteristic white-eye morphology, dominated by its distinctive, bold white eye-ring that contrasts sharply with its dark lores. Its plumage is a vibrant olive-green on the upperparts, transitioning to bright yellow on its throat, b...
This species primarily inhabits the canopy and understory of lowland primary forest and mature secondary growth on Ranongga Island, occasionally venturing into disturbed forest edges, from sea level up to around 860 meters.
Its diet primarily consists of small insects, including caterpillars and beetles, supplemented by nectar extracted from flowers and the pulp of small wild fruits and berries, actively gleaned from foliage and branches.
Ranongga White-eyes are highly active, arboreal birds, typically observed singly, in pairs, or small foraging flocks, and often participating in mixed-species feeding associations with other insectivores. They incessantly glean insects from foliage and bark, while also probing flowers for nectar....
The Ranongga White-eye's entire global distribution is astonishingly confined to a single, small volcanic landmass: Ranongga Island, located within the Western Province of the Solomon Islands archipelago. This extreme endemism means its breeding and year-round range is identical, spanning an area...
